T aZZ whom it may concern.-

Be it known that we, MARSHAL T. REEVES, JOHN N. KAILOR, and HARRY O.CLAY, citizens of the United States, residing at Columbus, in the countyof Bartholomew and State of Indiana, have invented anew and usefulPneumatic Stacker, of which the following is a specification.

Our invention relates to an improvement in pneumatic stackers.

The objects of our invention are to produce an improved form of hood forthe delivery end of a stackeretube; to provide improved means foroperating said hood, which means shall be independent of thelongitudinal move ment of the tube which carries the hood; to provideimproved means for operating the outer telescoping end of thedischarge-tube, and to provide such other improvements as shall bepointed out and claimed.

The accompanying drawings illustrate our invention.

Figure 1 is a side elevation. Fig. 2 is a vertical section on line 2 2,Fig. 1. Fig. 3 shows the shape of the several sections of sheet metalused in the construction of the hood. Fig. 4 is a central verticalsection of the discharge-tube, the hood being omitted. Fig. 5 is adetail from the under side.

In the drawings,-7 indicates a gear which forms the revoluble base ofthe stacker, and to this is secured an arc-shaped tubular sec tion 7.Mounted upon gear 7 are two arms 8, to the outer end of each of which ispivoted an arm 9. Between the outer ends of the arms 9 is the innerarc-shaped end 10 of the tube 11, the said end telescoping over thesection 7 in the usual manner. Telescoping over the main tube 11 is atubular section 12, the said section being supported by means of a pairof rollers 13 and 14, carried by the upper side of the section, and asimilar roller 15, carried at the inner end of the under side of saidsection. Rollers 13 and 14 rest and 0p crate in a chann'el16, carriedalong the upper side of tube 11 and extended somewhat beyond the outerend thereof, as shown in Fig. 4, and roller 15 rests within a similarchannel17, carried upon the under side of tube 11.

Rollers 14 and 15 are preferably vertically adjustable between a pair ofslotted cars 18. For the purpose of moving tube 12 back and forth uponthe tube 11 a Windlass 19 is mounted between arms 9 and provided with asuitable handle or crank 20. Secured to the windlass 19 is one end of acable 21, the said cable passing from the Windlass through an eye 22,carried upon the inside of the inner end of the tube 12, to which it issecured. The cable then passes forward and around a pulley 23, mountedupon the under side of the outer end of tube 11 and from there back to acollar 24, secured to and forming a part of the Windlass l9. Collar 24is rotatably adjustable upon the Windlass and is held in any desiredposition by means of a set-screw 25. By rotating collar 24 upon theWindlass the tension of the cable 21 may be easily and quickly adjusted.V

The outer end of the tube 12 is preferably beveled, and secured uponopposite sides thereof, near the outer end, are two brackets 26, towhich are pivoted the lower inner cor- 11ers of the first hood-section27, which is substantially semicylindrical in cross section, the lowerends of said section, however, being shorter than its middle. Pivoted tothe outer corners of the section 27 is the second hood-section 28. Theinner edge of the section .27 is preferably bound with astrengthening-band 29, which is extended beyond the pivot to form anarm, to which is attached one end of a spring 30, the other end of saidspring being secured to the tube 12. Itwill be understood, of course,that the spring 30 is duplicated upon the opposite side of the hoodsection. strengthened by a band 31, which is extended outside the pivot,and to this extended end is secured one end of a spring 32, the otherend of which is secured to the extended end of band 29. Secured to theupper side of band 31 is a cord 33, which is passed back through an eye34, carried by the tube 12, and secured to a winding pulley 35, mountedupon a stud-shaft secured to the side of the inner end of tube 12.Mounted in suitable bearings near pulley 35 is a worm 86, which mesheswith a gear 37, carried by said pulley. form 36 is provided with apolygonal axial open- The inner end of section 28 is also reeted at allof the angles desired.

ing, through which passes a polygonal shaft 38,'the inner end of whichis supported in a bearing 38, mounted upon the tube 11, and the outerend of which is supported by a bearing 39, carried by tube 12. For thepurpose of forming a long bearing for the outer end of shaft 38 a sleeve30 may be mounted between the bearing 39 and the bearings of the worm35. This sleeve 39' is rotatably mounted within its bearings, so that itrotates with the shaft, but is longitudinally movable upon said shaft.Secured to the inner end of shaft 38 is a suitable hand-wheel 40, bywhich it may be rotated.

The springs 30 and 32 tend normally to throw the two hood-sections intothe positions shown in full lines in Fig. 1, and in order to limit theoutward movement of each of said sections an eye 41 is secured to theupper side of band 29. Pivoted in this eye is one end of a rod or wire42, the other end of which passes through the eye 34 and is providedwith a head 44. Pivoted to the outer end of rod 42 or to the eye 41 isthe inner end of a second rod or wire 45, the outer end of which passesthrough an eye 46, carried by the band 31, and is provided with ahead47.

It is Well understood that it is not new to form a hood for thedischarge end of a stackertube of a series of semic'ylindrical sectionspivoted each to the section immediately preceding; but in all of suchconstructions it has been found very difficult to provide an arrangementby which the straw could be di- In the present construction we areenabled, owing to the peculiar shape of the hood-sections and by the useof but two such sections, to direct the straw atany angle between a linedrawn through the axis of the discharge-tube and a line drawn at leastone hundred and thirtyfive degrees from said line toward the rear. Inother words, supposing the hood-sections to be in the position shown infull lines in Fig. 1, the straw may be thrown back toward the separatorat an angle of from forty-five to thirty degrees from the horizontal. Inorder to accomplish this result, the two sections of the hood are formedin the following manner: The section 27 consists ofa single piece a, ofsheet metal, of substantially the shape shown in Fig. 3, the said piecehaving the two converging straight edges a and (1, and the curved edgesa and a, the edges a and a being designed to form the rear and forwardedges, respectively, of the completed section. Running in from the edgea are three parallel slits, forming apair of tongues a and 0. When thepiece a is bent into shape, the outer edges of the two tongues arelapped over the adjacent portions of the sheet, and the adjacent edgesof the two tongues are also lapped, thus forming in the completedsection the hump or bend a The section 23 is formed of the threesections b, c, and d. Thep'iece b is somewhat similar in shape to thepiece aand has the two converging straight edges I) and b the curvededge 6 along which the band 31 is to be secured, and the curved edge Z).Cut in from the edge I) are three parallel slits, forming the tonguesand 19 similar to the tongues of the piece a, and which are overlappedin the same manner to form the hump Z2 The piece 0 has the twoconverging straight edges 0 and 0 the curved edge 0 and the straightedge 0 The piece d is bounded by the two convex edges 01 and d Informing the section 28 edges 5 and c are riveted together, and the edges0 and (Z are also riveted together. \Vhen thus placed together, theedges 1), c, d, 0 and 12 form a U-shaped line (shown in Fig. 2) which inside elevation is substantially a straight line, as shown in Fig. 1. Bythis arrangement the piece (1 forms a snout for the end of the outersection.

In order to move the tube 12, the operator grasps crank 20, and byturning it in the desired direction the tube may be thrown forward ordrawn back. If there is any slack in the cable 21, it may be taken up byloosening screw 25, turning the collar 24:, and resetting the screw. Asthe tube 12 is moved back and forth the worm 36 slides freely over theshaft 38, so that the movement of said tube in no wise affects thehood-sections 27 and 28. To adjust the hood-sections, the operator turnshand-wheel 40, which, through the shaft 38, worm 36, gear 37, and pulley35, operates to wind or unwind the cord 33. In throwing up thehood-sections from the'position shown in full lines in Fig. 1 the firstpull on cord 33 swings the outer section 28 upon its pivot until it liesin the position indicated in dotted lines at 50, the upper inner edge ofsaid section coming into engagement with the section 27. A further pullupon cord 33 swings the two sections together about the pivot of section27 until the whole may be swung up into the position indicated in dottedlines at 51,the snoutd of the section 28 then lying above the medial oraxial line of the tube 12.

It will be noticed that the tube 12 is free to move back and forth uponthe tube 11 without disturbing the adjustment of the hoodsections andthat the two tubes 11 and 12 may be swung as a whole about the pivots ofarms 9 without affecting the positions of the hood-sections and withoutaffecting the relative positions of the two tubes.
